When Hamby heard this, she just couldn't believe her ears. She asked Hazelip if she was sure what she was talking about. Hazelip said yes. With that, they decided on a world trip. But because of COVID-19, they had to put off their trip. In January this year, the two got a start.
Hamby said their families were supportive of their big dream. "My daughter had no worries about my trip," Hamby said. "She was happy that I could live the life I wanted to live."
Hazelip wishes that their story could inspire (激励) people of all ages. "Don't sit in that chair and wait," she said. "If you don't use your time, you lose it."

2、河北省衡水市2025-2026学年上学期高二年级一调化学试题


A.2ΔH1＋2ΔH2-2ΔH3
B.ΔH1＋ΔH2-ΔH3
C.3ΔH1＋2ΔH2-2ΔH3
D.3ΔH1＋2ΔH2＋2ΔH3
答案　C
解析　根据盖斯定律，将反应①×3＋②×2-③×2可得反应4NH3(g)＋7O2(g)===4NO2(g)＋6H2O(g)　ΔH，则ΔH＝3ΔH1＋2ΔH2-2ΔH3，即C符合题意。
7.Diels Alder反应是一步完成的协同反应，也是立体专一的顺式加成反应。如图所示加成反应，生成两种主产物M、N，反应过程中的能量变化如图所示。下列说法正确的是(　　)


（2）请写出一个一定发生的反应的化学方程式______。
【答案】 ①. Al3+、Zn2+ ②.
【解析】
【详解】（1）金属活动性Al>Zn>Fe>Cu，滤液为无色则滤液无硝酸铜，Zn先与硝酸铜反应，且铝活性性最强，硝酸铝不能与锌、铁反应，所以滤液中一定有的金属离子为Al3+、Zn2+。
（2）金属活动性Al>Zn>Fe>Cu，向含有Cu（NO3）2和Al（NO3）3的混合溶液中加入一定量的铁粉和锌粉一定发生的反应是Zn与硝酸铜置换出铜，化学方程式：
19. 碳酸氢钠受热易分解，生成碳酸钠、水和二氧化碳，反应的化学方程式为________，充分加热10 g含碳酸钠的碳酸氢钠固体，反应前后固体中钠元素的质量分数之比为7:10，则生成水和二氧化碳的质量之和为__________g。
【答案】 ①. 2NaHCO3Na2CO3＋H2O＋CO2↑ ②. 3
